Application December 20, 1934, Serial No. 758,510

2 Claims.

This invention relates to hasps and has for its object to prevent thetwisting of a padlock upon the bolt member of the hasp in such a manneras to break the shackle of the padlock or otherwise hasp.

With these and other objects in view, the present invention consists inthe combination and arrangement of parts as will be hereinafter morefully described, illustrated in the accompanying drawing, andparticularly pointed out in the appended claims, it of course beingunderstood that changes in the form,

proportion, size and minor details may be made Within the scope of theclaims, without departing from the spirit or sacrificing any of theadvantages of the invention.

In the drawing:

Figure 1 is a front elevation of a hasp embodying the features of thepresent invention;

Figure 2 is a longitudinal section view on the line 22 of Figure 1 andFigure 3 is a cross section on the line 3-3 of Figure 1.

In the accompanying drawing there has been shown an ordinary haspincluding a base or attaching member I and a swinging latch member 2connected with the base member by a hinge 3. As is usual the base platemember I may be secured to a door frame 4 by suitable fastenings such asindicated at 5.

The swinging member 2 of the hasp is of a size to entirely cover thefront face of the base member I so that access to the fastenings 5 iseffectually prevented when the hasp is in use.

The member 2 is considerso as to overlap the door 6.

The outer free end portion of the swinging hasp member 2 is providedwith an opening I, preferably circular in shape, for the purpose ofreceiving a bolt 8 preferably circular in cross section and mounted uponthe door 6 so as to rotate freely upon the longitudinal axis of thebolt. As shown this bolt is mounted in a suitable casing 9 let into asocket or recess III provided in the outer face of the door, and securedto the door by suitable fastenings II which are covered by the outerfree end portion of the swinging hasp member 2 so that access to thefastenings is impossible when the hasp is in use.

is provided therefor.

The inner or rear end of the bolt is provided with an external annularflange I2 constituting an abutment cooperating with the casing toprevent outward removal or displacement of the bolt. The casing has anopening in its back wall to enable the assemblage of the bolt and itsmounting, and the flange I2 of the bolt engages the rear side of theantifriction bearing so as to prevent forward displacement of the bolt,the antifriction bearing being held by and between the front and back.walls of the casing against endwise movement of the bearinglongitudinally of the bolt. That portion of the belt which projectsoutwardly through the opening I is provided with an eye or opening I3 toreceive the shackle I4 of a suitable padlock I5.

When the hasp of the present invention is in use, it will operate in themanner of any ordinary hasp to hold the door closed. Should any attemptbe made to twist the lock upon the bolt for the purpose of breaking theshackle I4 or pulling it out of the padlock housing, the attempt to dothis will be frustrated because of the rotatable mounting of the bolt 8which will cause the padlock and the bolt to rotate together andtherefore it will be impossible to place any stress or strain on thepadlock sufficient to break the same away from the bolt. Moreover thesubstantially circular shape \of the opening I and the bolt 8 is suchthat the bolt will always rotate in the opening and there is nopossibility of the bolt and the swinging member 2 of the hasp beinginterlocked or interengaged against mutual independent movement so as tohold the bolt 8 against rotation and permit of the padlock beingforcibly twisted from the bolt.

What I claim is:

l. A keeper for a swinging hasp, comprising a substantially cylindricalbolt member adapted to rotatably fit a circular opening in the hasp andprovided at its outer end with an opening to receive the shackle of apadlock, and a mounting for the bolt, the maximum transverse boltportion outside of the mounting being less than the diameter of theopening in the swinging hasp member, said mounting including a casingro- 4 receive the shackle of a padlock, and a mounting for the bolt, themaximum transverse bolt portion outside of the mounting being less thanthe diameter of the opening in the swinging 'hasp member, said mountingincluding a casing having an opening in its front wall t-o rotatablyreceive the bolt, and an antifriction bearing for the 'bolt portionwithin the casing, said antifriction bearing being held by and betweenthe front and back walls of the casing, the rear end of the bolt beingprovided with an integral annular flange for engagement with the rearside of the antifriction bearing to prevent forward displacement of thebolt, the back wall of the casing being provided with an openingtoraccommodate the flange on the bolt.
